MagTool ATO is made to handle routine top-offs automatically, so maintaining the water level does not depend on adding water by hand each day. Its sensor-based operation is also useful when you are away for a short period and want the system to manage daily top-offs.\u003c\/p\u003e\n\u003ch3\u003eHow does MagTool ATO control the water level?\u003c\/h3\u003e\n\u003cp\u003eMagTool ATO uses two optical sensors to manage the refill cycle: the lower sensor detects a drop in water level and starts the pump, while the upper sensor detects the target level and stops filling. This automatic start-and-stop process is designed to keep the water level more stable as evaporation takes place. A separate intelligent safety program monitors filling time and stops operation when needed, providing an additional safeguard against overfilling.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe lower optical sensor triggers a refill when the water level falls.\u003c\/li\u003e\n\u003cli\u003eThe upper optical sensor signals the system to stop filling at the correct level.\u003c\/li\u003e\n\u003cli\u003eThe safety program monitors the duration of filling and can stop the system.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhich aquariums is this top-off system designed for?\u003c\/h3\u003e\n\u003cp\u003eMagTool ATO is suitable for reef, saltwater, freshwater, and planted aquariums. It is also intended for open-top aquariums, where faster evaporation can make regular water additions more frequent. The compact sensor measures 0.7 inches (about 2 cm), helping it take up minimal space within the aquarium setup.\u003c\/p\u003e\n\u003cp\u003eFor aquarium keepers, maintaining a steadier water level can reduce the need to add water manually as part of daily care. The system is designed for routine top-off rather than a one-time fill: the sensors detect changing water levels and control the refill cycle. MagTool provides a 1-year warranty for the ATO system.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSuitable for reef, saltwater, freshwater, and planted aquarium setups.\u003c\/li\u003e\n\u003cli\u003eDesigned to help manage evaporation in open-top aquariums.\u003c\/li\u003e\n\u003cli\u003eSensor size: 0.7 inches (about 2 cm).\u003c\/li\u003e\n\u003cli\u003eManufacturer warranty: 1 year.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat comes in the MagTool ATO kit?\u003c\/h3\u003e\n\u003cp\u003eThe kit contains a 12V DC water pump measuring 1.5 × 1.5 × 2.0 inches (3.8 × 3.8 × 5.1 cm), with a 74 GPH flow rate (280 L\/h) and an 8.2 ft maximum head height (2.5 m). It also includes a power adapter, anti-siphon check valve, 1.5 m water tube (4.9 ft), mounting bracket, controller, and user manual.

The dual-sensor refill cycle starts when the water level drops and stops when the correct level is reached; the filling-time safety program can also stop operation when needed. It is designed to reduce the need to ask someone to check and top off the aquarium during a short trip or business absence.\u003c\/p\u003e\n\u003cp\u003eMagTool ATO is suited to aquarium keepers who want automatic daily top-offs across reef, saltwater, freshwater, or planted setups, especially open-top aquariums with faster evaporation.
